Abstract

A device for air/gas removal in a water heating system comprising a top section A, and a bottom section D. Section A may have a domed top, a bottom connection point C, and an upper air outlet or vent B, whilst section D may be of a curved, conical shape and may have an upper connection point E, an inlet for water or process working fluid F, and a lower outlet for water or process working fluid G. The device may be formed of machinable or mouldable metals and/or plastics and can be used in a closed loop water heating system. The device may use rotational flow to separate air/gas from working fluids, which may exit the device via a vent.

Description

DESCRIPTION

Airgon The oreseni invention relates to de-aeration devices of the type to be used for removal of unwanted dissolved gases within a dosed loop heating system for space heating or process heat.

BACKGROUND OF THE INVENTION

Deaeration units for remove.: from process fluids are varied and are used in systems ranging from domestic heating up to and Radix-Dag industrial process fluid deaeration such as air/gas removal from power generation steam plants One type of de-aerator as disclosed in US Patent -U52017059251 directed to an industrial design consisting of multiple components often consisting of a spray mechanism, a dertieste.d or shared tsource, and iniet for the working fluid to be process and separate outlets for the removed air/gas and the now deaerated process fluid.

A rie-aerator as dtsciosed in US Patent -U$2010019054 directed to a de-aerator that is manufactured as a single preassembled unit and which reason the mechanical and tnermat properties of the heating system and working fluid to facititate operaiton. This type of de-aerator is primarily for smatter systems typicalty in space heating applications.

The units typically operate via heat differentials: centrifugal forces: pressure differentials, fluid agitation, or some combination of the aforementioned aspects.

A patent as disclosed in US Patent -US2015321122 directed to a de-aerator specifically designed for a water heating system that comprises of an in:et and outlet for fluid, and an air outlet for extracted gases as is typical of all systems regardless of complexity. The de-aerator has a curvature of an increasing angle which terminates at the fluid outlet providing a gradual increase in rotation of water creating a vortex flow which is indicated to be a necessary attribute for the correct operation of the device and rernovai of dissolved gases.

An important consideration for de-aerator units is the breaking of surface tension and the provision of conditions which encourage or allow for the separation of air/gases from the working fluid solution in which it is entrained.

Another consideration is the temperature, pressure: and flow requirements in which the de-aerator will be operation: and the fluid type and specific appiication in which it will he operating.

SUMMARY OF THE INVENTION

According to the present invention there is provided an improved deaeration system wherein the deaeration is manufactured as a kit and provides for cost savings, improved environmental considerations as well as greater ease of inspection of parts prior to instaliation for service.

According to the present invention there is provided a deaeration system kit comprising a top dome shaped top section with alrigas outlet allowing for the insertion of a gas vent tube and standard plumbing and heating unidirectional airtgas vent a bottom sectliat comprising a working fluid inlet that allows for the tritlow of working fluidiwafer and which encourages the creation of a rotational flow of water along the inner surface immediately upon entry into the assembled unit. and a curved conical shape terminating at the bottom of the section at the working fluid outlet.

The dome shaped top section starts at the top with an opening for a air vent and Gas evacuation tube to be inserted It curves out and away in a dome like shape and ends at its bottom with a connection point being an area of reduced wall thickness for connection to the Soften: gertrion during assembly in::: :rerna:8:flay he bC:ttegT: SE:Clb:),1 The tixiitorit section hex:Ain:rid with a reduced thickness top for connection to the top section down with an extrusion of material at one point approximately half way down the outer body of the bottom etotion for the purpose of providing a working fluid/water inlet.

The bottom section beginning with a section of reduced wall thickness tor connection to Inc top section and continuing away with progressively smalier diameter in a non iinear curve and terminating in a working fluid/water outlet.

The pleS 3Veniien with the top ser.-tiOn, and bottom section once fuliy assembied or rises of a working fluid inlet, a working fluid outiet, and a vent tube with unidirectional air vent, and an internal vessel cavity that provides for the necessary conditions for the encouragement ot gas reimovai from the working fluid and subsequent removai of said gas fiorn the internal chamber through the vent tube and later through the unidireictiortal air vent.
